Does anyone know what 망가 this is?

The story revolves around a teenage boy. He lives in a family with two twin little brothers and I'm not 100% sure but I think he also has two older brothers. He goes to this fancy school on scholarship where he meets this really rich guy. This other guy falls in 사랑 with him and at one point forces him to do things. Anyway I read this a while back and have been looking everywhere and can't seem to find it. The two twin little brothers are marked into my brain because they were really cute so if 당신 know which one this is please let me know.
